Differentiate between real and virtual image?
Answers
Explanation:
REAL IMAGE -
1. REAL IMAGE IS FORMED BY ACTUAL INTERSECTION OF LIGHT RAYS.
2. REAL IMAGE CAN BE OBTAINED ON A SCREEN.
3. REAL IMAGE IS FORMED IN FRONT OF A MIRROR.
4. REAL IMAGE IS ALWAYS INVERTED.
VIRTUAL IMAGE -
1. VIRTUAL IMAGE IS FORMED BY IMAGINARY INTERSECTION OF LIGHT RAYS.
2. VIRTUAL IMAGE CANNOT BE OBTAINED ON A SCREEN.
3. VIRTUAL IMAGES FORMED BEHIND THE MIRROR.
4. VIRTUAL IMAGE IS ALWAYS ERECT ( i.e., upright)
Answer:
To obtain a real image the light source and the screen must be placed on the same plane. The image is obtained by using a converging lens or a concave mirror. The size of the image depends upon the placement of the object.
The virtual image, on the other hand, is an upright image that can be achieved where the rays seem to diverge but do not converge in reality. This image can be produced with the help of a diverging lens or a convex mirror.
